The Migraine Disability Assessment (MIDAS) Questionnaire: Translation and Reliability of the Italian Version

We have developed and tested an Italian version of the Migraine Disability Assessment (MIDAS) questionnaire, an established instrument for assessing headache-related disability. A multistep process was used to translate and adapt the questionnaire into Italian, which was then tested on 109 Italian migraine without aura patients, 86 (78.9%) of whom completed the form a second time 21 days later. Overall MIDAS score had good test–retest reliability (Spearmans correlation 0.77), closely similar to that found in English-speaking migraineurs, and individual responses were also satisfactorily reliable. Internal consistency was good (Cronbachs alpha 0.7). These findings support the use of the MIDAS questionnaire as a clinical and research tool with Italian patients.

Underdiagnosis and undertreatment of migraine in Italy: a survey of patients attending for the first time 10 headache centres.

The aim of this study was to asses the clinical features, pattern of healthcare and drug utilization of migraine patients attending 10 Italian headache centres (HC). Migraine is underdiagnosed and undertreated everywhere throughout the world, despite its considerable burden. Migraine sufferers often deal with their problem alone using self-prescribing drugs, whereas triptans are used by a small proportion of patients. All patients attending for the first time 10 Italian HCs over a 3-month period were screened for migraine. Migraine patients underwent a structured direct interview about previous migraine diagnosis, comorbidity, headache treatments and their side-effects and healthcare utilization for migraine. Patient satisfaction with their usual therapy for the migraine attack was evaluated with the Migraine-Assessment of Current Therapy (ACT) questionnaire. The quality of life of migraine patients was assessed by mean of Short Form (SF)-12 and Migraine-Specific Quality of life (MSQ) version 2.1 questionnaires. Of the 2675 patients who attended HCs for the first time during the study period, 71% received a diagnosis of migraine and the first 953 subjects completed the study out of 1025 patients enrolled. Only 26.8% of migraine patients had a previous diagnosis of migraine; 62.4% of them visited their general practitioner (GP) in the last year, 38.2% saw a specialist for headache, 23% attended an Emergency Department and 4.5% were admitted to hospital for migraine; 82.8% of patients used non-specific drugs for migraine attacks, whereas 17.2% used triptans and only 4.8% used a preventive migraine medication. Triptans were used by 46.4% of patients with a previous diagnosis of migraine. About 80% of migraine patients took over-the-counter medications. The Migraine-ACT revealed that 60% of patients needed a change in their treatment of migraine attacks, 85% of whom took non-specific drugs. Both the MSQ version 2.1 and the SF-12 questionnaires indicated a poor quality of life of most patients. Migraine represents the prevalent headache diagnosis in Italian HCs. Migraine is still underdiagnosed in Italy and migraine patients receive a suboptimal medical approach in our country, despite the healthcare utilization of migraine subjects being noteworthy. A cooperative network involving GPs, neurologists and headache specialists is strongly desirable in order to improve long-term migraine management in Italy.

EEG features in juvenile migraine: topographic analysis of spontaneous and visual evoked brain electrical activity: a comparison with adult migraine.

Topographic analysis of spontaneous and steady-state visual evoked brain electrical activity was carried out between attacks in 82 migraine patients (40 youths and 42 adults). In adult migraine with aura a significant increase of delta rhythm percentage power was observed compared with migraine without aura and age-matched controls. Children suffering from migraine both with aura and without aura had an increased theta rhythm compared to normal controls. The presence of alpha interhemispheric asymmetry discriminated between migraine with aura and without aura, just as in adults. An increased amplitude of the SVEP F1 component with a tendency to the spread of visual reactivity was observed in juvenile migraine with and without aura; this pattern was not dissimilar from the one previously observed in adult migraine with and without aura. Abnormal photic driving in migraine is independent of age and type of migraine.

Headache and anxiety–depressive disorder comorbidity: the HADAS study

Psychiatric comorbidity (prevalence and types) was tested in a naturalistic sample of adult patients with pure migraine without aura, and in two control groups of patients, one experiencing pure tension-type headache and the other combined migraine and tension-type headaches. The study population included 374 patients (158, 110 and 106) from nine Italian secondary and tertiary centres. Psychiatric comorbidity was recorded through structured interview and also screened with the Mini International Neuropsychiatry Interview (MINI). Only anxiety and depression were investigated. Psychiatric disorders were reported by 49 patients (14.6%; 10.9% of patients with migraine, 12.8% of those with tension-type headache and 21.4% of those with combined migraine and tension-type headaches). The MINI interview detected a depressive episode in 59.9% of patients with migraine, 68.3% of patients with tension-type headache and 69.6% of patients with combined migraine and tension-type headaches. Depression subtypes were significantly different across groups (p=0.03). Anxiety (mostly generalised) was reported by 18.4% of patients with migraine, 19.3% of patients with tension-type headache, and 18.4% of patients with combined migraine and tension-type headaches. The values for panic disturbance were 12.7, 5.5 and 14.2, and those for obsessive–compulsive disorders were 2.3, 1.1 and 9.4% (p=0.009). Based on these results, psychopathology of primary headache can be a reflection of the burden of the disease rather than a hallmark of a specific headache category.

Coexistence of TACS and Trigeminal Neuralgia: Pathophysiological Conjectures

Background.—Trigeminal autonomic cephalgias (TACs) and trigeminal neuralgia are short‐lasting unilateral primary headaches whose study is providing insights into craniofacial pain mechanisms. We report on 2 patients in whom trigeminal neuralgia coexists with the TACs paroxysmal hemicrania and SUNCT.

Stress and chronic headache

Abstract The aims of this study were to assess how stress affects chronic headaches, and in particular to determine whether events play a role in the transformation of an episodic headache into a chronic form. A population of 267 Italian patients with chronic headache (headache present on average more than 15 days per month) was studied. Our results confirm a triggering role of stress on headache. We also found that episodic headache (migraine in most patients, 74.1%) preceded the development of a chronic form in about 90% cases. Among these patients, in 44.8% a stressful event correlated with the transformation. Analysis of these events revealed that minor events played a greater role than major life events, suggesting that patients with transformed headache are characterised by a different way of reacting to stress.

Topographic analysis of steady-state visual evoked potentials (SVEPs) in the medium frequency range in migraine with and without aura.

Topographic analysis of SVEPs in the medium frequencies range was performed in 30 migraineurs without aura, 20 migraineurs with aura and in 20 control subjects. The mean absolute power values of the fundamental component F1, the subharmonic F1/2 and the first harmonic F2, corrected by logarithmic transformation, were computed in each group and then compared using Students t-test. The interhemispheric coherence of the F1 component was also evaluated. The 18, 21 and 27 Hz F1 components were increased in both migraineurs with and without aura, particularly in the temporo-parietal regions. The 24 Hz F1 component was augmented only in migraineurs without aura in the parieto-occipital regions in comparison with migraineurs with aura and controls. Migraine with aura patients had a reduced interhemispheric coherence mostly of 12 Hz and 15 Hz F1 components in frontal and temporo-parietal regions. Results of the study confirm abnormalities of SVEPs in migraineurs with and without aura. These consist of widespread increases of F1 components in the medium frequency range over the temporo-parietal regions.

Psychologic factors in chronic headache: assessment by means of the SCL-90-R inventory.

Headache, has been carried out with the symptom check list (SCL)-90-R inventory. The results obtained were viewed in relation to sex, age, illness onset, and illness duration. Females showed a positive correlation of somatization with present age and with age at onset of illness and a negative correlation of interpersonal sensitivity, hostility, and paranoid ideation with present age and age at onset of illness. Men showed a negative correlation of obsessive-compulsive and paranoid scores with age and a positive correlation between onset of illness and somatization. Data were also analyzed by cluster analysis, which showed underpopulation with peculiar patterns of symptom profile. A prospective, long-term epidemiologic study could provide more conclusive results.

Effects of amitriptyline and intra-oral device appliance on clinical and laser-evoked potentials features in chronic tension-type headache

In the present study, we examined clinical and laser-evoked potentials (LEP) features in two groups of chronic tension-type headache (CTTH) patients treated with two different approaches: intra-oral appliance of prosthesis, aiming to reduce muscular tenderness, and 10 mg daily amitriptyline. Eighteen patients suffering from CTTH (IHS, 2004) participated in the study. We performed a basal evaluation of clinical features and LEPs in all patients (T0) vs. 12 age- and sex-matched controls; successively, patients were randomly assigned to a two-month treatment by amitriptyline or intra-oral device appliance. The later LEPs, especially the P2 component, were significantly increased in amplitude in the CTTH group. Both the intra-oral prosthesis and amitriptyline significantly reduced headache frequency. Total Tenderness Score was significantly reduced in the group treated by the prosthesis. The amplitude of P2 response elicited by stimulation of pericranial zones showed a reduction after amitriptyline treatment. The results of this study may confirm that pericranial tenderness is primarily a phenomenon initiating a self-perpetuating circuit, favoured by central sensitisation at the level of the cortical nociceptive areas devoted to the attentive and emotive compounds of pain. Both the interventions at the peripheral and central levels may interrupt this reverberating circuit, improving the outcome of headache.

Workplace disability in migraine: an Italian experience

Abstract.Workplace disability due to migraine has not been extensively researched in non-English speaking countries. We assessed the repercussions of headache, and particularly of migraine, on work in a sample of employees from an Italian company (Bulgari). Information was obtained through a self-answering questionnaire in “all headaches” sufferers, and through direct interview in migraine sufferers (diagnosis according to IHS criteria). Headache frequency, pain intensity and headache-related disability were higher in migraineurs than in “all headaches” sufferers. About a quarter of migraineurs missed at least one day in the three months prior to the interview due to headache, and around 10% lost two or more days over the same period. Moore than 50% of migraineurs reported 1–7 days per month at work with headache, with reduction in productivity level by 50% or more in 15% of respondents. Our data confirmed that headaches, and particularly migraine, cause a considerable reduction in workplace productivity. Workplace interventions to effectively manage migraine are needed.
